The direct labour cost per unit has been based on an expected learning rate of 90% but now the finance director has realised that a 95% learning rate should be applied.
The answer: The target cost will remain the same and the cost gap will increase.
My question: Why does the cost gap increase? Is it because a higher learning rate means they are learning more on the job? Learning more on the job means they are slower and less efficient, thus increases cost.
As I explain in my free lectures on this, a higher learning rate means that they are learning less. (A learning rate of 100% would mean that they were not learning at all!)
